2. Description of the Related Art As shown in FIG.
Is formed by attaching a metal frame 5 composed of a plurality of vertical frames 3 and a plurality of horizontal frames 4 to the back side of a panel body 2 made of lightweight concrete or the like containing air bubbles. When transporting the outer wall panel 1 to the construction site or storing it at the construction site, as shown in FIGS. By using two holding members 6 on the upper end side and the lower end side, these holding members 6 are vertically stacked to maintain a predetermined vertical interval between two adjacent upper and lower outer wall panels 1. Meanwhile, a plurality of outer wall panels 1 are stacked vertically and held in a horizontal posture.

As shown in FIG. 11, each holding member 6
It comprises a horizontal bar 7 slightly longer than the left and right width of the outer wall panel 1 and spacing members 8 fixed to both ends of the horizontal bar 7, and the horizontal bar 7 has a vertical U-shaped vertical cross section. . On the other hand, each of the spacing members 8 has a standing wall portion 8a having a U-shaped horizontal cross section that is open outward, a lower wall portion 8b extending horizontally at a lower end portion of the standing wall portion 8a, and a horizontal extending portion at an upper end portion of the standing wall portion 8a. A hole 8d is provided in the lower wall 8b, and a pin 8e projecting upward is integrally provided at a position corresponding to the hole 8d in the upper wall 8c.

As shown in FIGS. 9 and 10, a plurality of holding members 6 are provided.
Are stacked vertically, the upper holding member 6 is detachably connected by fitting the hole 8d of the upper holding member 6 to the pin 8e of the lower holding member 6, and the holding member 6 of each stage is separated. By placing one outer wall panel 1 on each of the horizontal bars 7, the upper and lower outer wall panels 1 can be held in a non-contact state with each other.

At a building site, when the uppermost outer wall panel 1 is sequentially lifted by a crane and transported to a mounting position, for example, an outer wall hook 10 as shown in FIG.
